PALO ALTO, U.S. -- Tesla has revealed a new battery to boost electric cars' power and range, saying the units will help to drive vehicle costs down to $25,000 within a few years.
The battery cell is larger than those Tesla buys from Japan's Panasonic and other suppliers and will be produced partly by the electric automaker itself -- a first for Tesla. The battery will provide six times more power and enable a 16% range increase for vehicles, the U.S. electric automaker said.
